I called my electric company, and they told me that my citys rate is .711 kwh. But when i calc, it comes out saying its $383 a month to run my 1000 watt hps on 18 hours a day. Did i hear them wrong or something? Can anyone tell me how many kwh you guys get cause this just doesn't seem right to me.

It is not possible your paying 71 cents a kilowatt hour. You definately got wrong information. I'm east coast and I'm paying 15 cents a kilowatt hour. Take a look at your electric bill. It will tell you what your paying . You should see what the distributer charges. That number is gonna be low. Probally about 5 cents a kilowatt hour. Then you have a price from your actual electric company. Probally about 10 cents a killowatt hour. That gives you a total of 15 cents a kilowatt hour. You can definately relax a bit. 71 cents is DEFINATELY wrong.

Thats probally just the electrical company's charge. There will also be a delivery charge as well. Not much though. Probally about 5 cents.
the .71 may be per 100,000 kwh not per kwh
don't know with out seeing electric bill easy rule of thumb check old summer bill with AC on 24/7 if ac eats 1000 watts or better and you compare with spring month with few electric
heaters you'll have idea on what a grow using 1000-1500 watts
24/7 will cost
you might be more costeffective to use two[2] 400's in there both for costs and for better light penetration i'm great lakes area and my system [400] might be 20$ added a month haven't checked bills any how since i got HID light i changed out
most bulbs in the house for cfl's helped a little to keep power load fairly even last i compared bills couple months ago
easy electric guide look at power consumption plate in specs or on back of tv's computers freezers etc and lookat energy rating
bill change from a 475 watt freezer is about equal to a 400 HID plus vent fans
same goes for 1500 watt AC vs 1000 watt HID with venting
not science class acceptable but a good predictable economic guess/theory
any time you see cost estimates for freezers or AC if wattage is close to a grow light size you have approximate estimate on cost during 24 day cycles
during budding time day cycle is half so cost is less....

My cost here in Washington is .0596. According to this site:Grow Light Operating Cost - Greentrees Hydroponics
My electric bill for a 1000w hps on 12/12 is about $24.

That seems very low. Are you sure that's not just the delivery charge?

I live in washington as well and my cost is .076
Nope >.0596/kWh plus .50 a day customer charge plus 2.14% state sales tax.
You have to get your bill and look at ALL the charges per Kw hr
I am in the Boston area and it is like a total of 13.5 cents per Kwh
Easiest way to figure a true estimate is to take last months bill, divide it by hours you use and you will get the true cost per hour. You can then use the cool matrix to figure your costs
